Current Conditions at 3 p.m. EST this Friday afternoon: There is a brief lull in the winds but it remains cold as temperatures struggle in the upper 20s. Fine particle pollution (PM2.5) concentrations are well down inside the good range. A clipper system is expected to bring a small accumulation of snow to the area late Saturday and Saturday night, followed by an Arctic blast Sunday into Monday. Moderate air quality occurs in parts of the area Saturday, with lower PM2.5 to follow Sunday and Monday. A warmup finally comes to pass by the middle of the week, with precipitation possibly in liquid form Wednesday night. Here are the forecast details: *** Saturday’s forecast: Mostly cloudy Saturday with snow arriving during the late afternoon. PM2.5 will be highest during the morning, with an overall average for the day in the lower moderate range. Total snow accumulations will be an inch or two. *** Sunday’s forecast: Windy and frigid Sunday with snow tapering off to snow showers. Highs will be held to the upper teens with near zero wind chills. PM2.5 levels will fall well down inside the good range. *** Monday’s forecast: Mostly cloudy with a little less wind Monday, but still cold as temperatures hold in the lower 20s. Air quality will remain in the good range. *** Extended forecast: As the upper level flow turns westerly by the mid-week period, a warming trend will commence. Warmer air influx often results in higher humidity, which leads to fine particle increases, so moderate air quality is predicted for the Wednesday-Thursday time frame. Precipitation in the form of rain is possible Wednesday night into Thursday.---McAuliffe
